Fast page mode is a modification of an older idea called Page Mode. To begin I will explain what page mode is and how fast page mode was made better. Page mode is a special access mode that enables an entire "page" of data to be held at one time. This would now allow column addresses to read from the held page without waiting for row address setup. Fast page mode made the improvement by removing the column address setup time during the page cycle. This mode is still being used in many systems because there is a reduced power consumption in memory. Although because of several drawbacks, FPM is not in any demand and is least desirable of the available DRAM memory types."
